ergonomics

This term describes the intersection of human biology and engineering, focusing on the harmony between a user and their environment. It carries a professional, technical connotation, typically appearing in corporate, medical, or industrial contexts where efficiency and health are prioritized over aesthetics.

Despite ending in s, the word is treated as a singular mass noun referring to a field of study. It does not have a plural form and cannot be counted as individual units; one does not refer to multiple ergonomics, but rather to ergonomic principles or an ergonomic setup.
